PACOT
Can anyone tell me how's the PACOT work? For example, the CPA828, 882, 838, 082 would track via A1/M750 to Tokyo FIR, will they then take different tracks to cross the Pacific? I'm thinking that if 3 CPA a/c bound for North America, no.1 takes FL290 initially, no. 2 takes FL270, and no. 3 takes FL250 (to avoid delay on ground), and assuming they are of the same a/c type (not much speed difference) and depart in a row (no longitudinal separation), even when the no.1 can climb to FL370 upon leaving Tokyo FIR, the no. 3 can only get FL290. Is that true?
